2. AN APPARATUS FOR INDICATING THE REFERENCE PATTERN THAT IS SIMILAR TO A SPECIMEN IN A SPECIMEN IDENTIFICATION SYSTEM UTILIZING COMPARISON OF A FUNCTION OF THE SPECIMEN F(S) TO FUNCTIONS OF REFERENCE PATTERNS F(R) WHERE AT LEAST ONE PLURALITY OF SAID FUNCTIONS OF THE REFERENCE PATTERNS F(R) ARE IDENTICAL, COMPRISING, IN COMBINATION: MEANS FOR GENERATING SAID FUNCTION OF THE SPECIMEN F(S); MEANS FOR COMPARING SAID FUNCTION OF THE SPECIMEN F(S) WITH SAID FUNCTIONS OF REFERENCE PATTERNS F(R) TO UNIQUELY IDENTIFY SAID SPECIMEN WHEN THE SPECIMEN IS SIMILAR TO A REFERENCE PATTERN WHOSE FUNCTION F(R) IS UNIQUE, AND TO AMBIGUOUSLY IDENTIFY THE SPECIMEN TO BE SIMILAR TO ONE OF PLURALITY OF REFERENCE PATTERNS HAVING IDENTICAL FUNCTIONS F(R) WHEN UNIQUE IDENTIFICATION IS NOT INDICATED; MEANS FOR GENERATING A SECOND FUNCTION OF THE SPECIMEN F''(S) THAT IS UNIQUE FOR ALL SPECIMEN THAT ARE SIMILAR TO ANY REFERENCE PATTERN IN A PLURALITY OF REFERENCE PATTERNS HAVING IDENTICAL FUNCTIONS F(R); AND MEANS FOR COMPARING SAID SECOND FUNCTION OF THE SPECIMEN F''(S) WITH SECOND FUNCTIONS F''(R) OF SAID IDENTIFIED PLURALITY OF REFERENCE PATTERNS, TO UNIQUELY IDENTIFY THE SPECIMEN.
